FIELD OF THE INVENTION

The present invention relates to the field of bathroom accessories, in particular to a faucet shell and faucet made of such shell.

BACKGROUND OF THE INVENTION

Faucet series play a major part in bathroom accessories, and faucets in their sub-series have various small types. Existing faucet shell castings are almost solid and produced with a large quantity of materials. Their valve element mounting positions are generally arranged integrally with shells, requiring valve element mounting positions and connecting structure of inlet and outlet pipes to be processed on the shell after casting with extremely high material and production costs. In addition, the outer wall of faucet shells needs to be processed with complicated technologies, increasing production steps, costs and labor intensity, even transportation cost due to heavier faucet shells.

SUMMARY OF THE INVENTION

In order to solve the above problems, the present invention is proposed to provide a faucet shell and faucet made of such shell that can effectively reduce supporting facilities required, production processes and dependence on large production equipment so as to reduce production cost and exhibit beautiful appearance.

To solve the above problems, the present invention provides the following technical scheme: a faucet shell, comprising a cylinder body formed by cutting tubular profile, and a cover formed by punching from sheet plate. The outer edge of the cover is welded to the upper end face of the cylinder body or inner wall of the upper end of the cylinder body. A through hole is arranged in the center of the cover, and a valve element mounting cylinder is welded at the through hole.

The above structure shows that the cylinder body is formed by directly cutting from tubular profiles such as stainless-steel pipe and aluminum pipe, and the cover is formed by punching from stainless steel plate, aluminum plate or other plates. The outer edge of the cover is preferably welded to the inner wall of the cylinder body at its upper end and kept neatly flush with the end face of the cylinder body. The through hole is arranged in the center of the cover for welding the valve element mounting cylinder. Since the positional relationship between the valve element mounting cylinder and the through hole can be adjusted by movement before assembly, the overhangs of the valve element mounting cylinder can be controlled according to different faucet models to ensure the overall aesthetics and coordination after faucet assembly and avoid one-mold-one-object defect existing in casting process; the overall faucet shell is formed by welding the cover punched from sheet plate to effectively avoid many problems in existing faucet shell casting process and follow-up overall surface polishing and electroplating, such as complicated production process, high production cost, and low production efficiency, thus to effectively reduce production cost, lower finished faucet prices, and increase competitiveness while the appearance, performance and corrosion resistance remain unchanged.

Further, the present invention proposes that a welding cylinder formed by punching and drawing material in the hole is arranged at the through hole in the center of the cover, the welding cylinder extends toward the lower end of the cylinder body, the outer wall of the valve element mounting cylinder is welded to the welding cylinder, and an opening is arranged at one end of the valve element mounting cylinder facing the upper end face of the cylinder body.

The above structure shows that when the through hole is punched out from the cover, the welding cylinder is produced by reasonably drawing the material in the through hole for welding the valve element mounting cylinder, so as to ensure the overall strength and rigidity of the cover, and the valve element mounting cylinder is used for mounting the valve element.

Further, the present invention proposes that a closing is arranged at the extended end of the welding cylinder, the outer wall of the valve element mounting cylinder is welded to the closing, and the outer wall of the valve element mounting cylinder is spaced apart from the inner wall of the welding cylinder.

The above structure shows that the closing can ensure the smooth welding of the welding cylinder to the valve element mounting cylinder, and reduce the risk of penetration welding.

The bottom cover is integrally welded to the valve element mounting cylinder to form a cavity for placing the valve element later. The valve element is placed against the bottom cover and connected to the inlet pipes thus to control the on-off of water flow between the inlet pipe and the water outlet to allow water to flow from the water outlet into the interlayer between the welding cylinder and the valve element mounting cylinder; the inlet pipes comprise a cold water pipe and a hot water pipe. A hot and cold water valve element can be used to adjust the temperature of outlet water to match hot and cold water faucets.

Further, the present invention proposes that a valve element locating hole formed by punching is arranged on one side of the bottom cover facing the inner cavity of the valve element mounting cylinder.
